SIDE FRAME.

Application filed August 7, 1915.

To 11/! I/lmm ("if may con crii.

Be it known that I. IIARHY L. Annex, a citizen of the United States. and resident of Alliance. in the county ot Stark and State of ()hio. have invented certain new and use t'ul Improvements in Side Fran'ies, of which the following is a specification.

Ely-invention relates to car trucks, and has particular reference to a novel side frame for :se in connection therewith.

it has been found (ltfill'illll. and expedient to form the side frames of car trucks as a single casting. However, as these castings are made in steel. many dilliculties have been experienced in the production of sound eastings and in the provision oi a design which shall at the same time permitol the prodnc tion of sound castings and give requisite strength vertically and transversely.

in the construction shown, an object is to provide a side frame which may be cast to advantage and which shall combine the requisites ol' lightness and strength against vertical and transverse stresses. This result is secured by adopting the closed box form for the entire lrame. in other words. the ilbtlllg comprises in cll'ert two vertical webs of the proper shape. which webs are joined by transverse webs. thus l'orniiug a.closed box at any points through which a section is taken.

The invention will be more readily understood by reference to the accom uniying drawings. wherein- Figure l is a front elevation of a side lrame constructed in accordance with my invention: Fig. 2 is a plan view thereof. and Fig. I) is a section on the line 3-3 of Fig. 1.

Referring; more particularly to the drawings. it will beseen that the side frame cona j sisls essentially ol a casting having a coniprcssion member 10, tension member 11 struts 125 and journal box engaging portions 13. Described in that way, the frame cone prises two webs of the shape shown in Fig. 1, one web being disposed behind the other, and these webs being joined by transverse webs to form an integral structure having a cored or hollowed out interior. As a means for setting the cores and cleaning the cast- Specification of Letters Patent.

ing. I may provide the transverse open? ll and the vertical (l}')Ll1ll1,{S 1.5. the latter being formed in the compression menmer 10.

Similar openings 16 will be provided in the end pieces 13. for the aecommodatiou of journal box bolts. To permit the entrance of the journal box bolt. 1 cut out a portion of the compression member at the ends, as indicated at 1T, 18. in Fig. 2.

The construction is capable of some mot lilication. and such modifications are Within the scope of my claims I consider within the spirit ol my inv *ntion.

In a side frame, the combination o compression member. tension. memo r Y strut arranged in truss to the strin' of said parts including two wela; st v the form of the side frame. th' edges of t; two webs being joined by continuous webs, thereby producing a box-shaped brain and provided in its compression and tension members with openings. said openings serw ing as a means for supporting the. cores and for cleaning the sand from the interior of the box alter the casting has been formed. substantially as described.
